Switch all tools OFF before connecting them to a power supply.Disconnect and lockout the power supply before completing any maintenance work tasks or making adjustments.Ensure tools are properly grounded or double-insulated. The grounded equipment must have an approved 3-wire cord with a 3-prong plug. This plug should be plugged in a properly grounded 3-pole outlet.Test all tools for effective grounding with a continuity tester or a Ground Fault Circuit Interrupter (GFCI) before useDo not bypass

Keep power cords clear of tools during use.Suspend extension cords temporarily during use over aisles or work areas to eliminate stumbling or tripping hazards.Replace open front plugs with dead front plugs. Dead front plugs are sealed and present less danger of shock or short circuit.Do not use light duty extension cords in a non-residential situation.Do not carry or lift up electrical equipment by the power cord.Do not tie cords in tight knots. Knots can cause short circuits and shocks. Loop th

A Class A Ground Fault Circuit Interrupter (GFCI) works by detecting any loss of electrical current in a circuit (e.g., it will trip at a maximum of 6mA). When a loss is detected, the GFCI turns the electricity off before severe injuries or electrocution can occur. A painful non-fatal shock may occur during the time that it takes for the GFCI to cut off the electricity so it is important to use the GFCI as an extra protective measure rather than a replacement for safe work practices.GFCI wall ou

It is important that you follow the manufacturer's instructions with respect to the use of a GFCI. Test permanently wired GFCIs monthly, and portable devices before each use. Press the "test" and "reset" buttons. Plug a "night light" or lamp into the GFCI-protected wall outlet (the light should turn on), then press the "TEST" button on the GFCI. If the GFCI is working properly, the light should go out. If not, have the GFCI repaired or replaced. Press the "RESET" button on the GFCI to restore p
